A brief guide to some commonly used statistical symbols:
WebThe population means is the mean or average of all values in the given population. It is calculated by the sum of all values in the population, denoted by the summation of X divided by the number of population values denoted by N. It arrives by summing up all the observations in the group and dividing the summation by the number of observations.
